Automobilista 2: mid-corner understeer — what to change

What it feels like

Mid-corner, at steady speed, the car refuses to hold the line and you have to unwind the wheel.

Why it happens and what we're after

Mid-corner understeer: shift balance forward (softer front bar, stiffer rear) and add front camber for more lateral grip.

What to change, exactly

Ranges, steps and defaults are the REAL ones for this sim. The amount is expressed in the game's own unit so you can apply it without converting anything.

Parameters flagged as “estimated range” do not come from a verified in-game capture: the direction of the change is right, the exact magnitude may differ on your car.

  1. 1.Front anti-roll bar

    Lower ↓ by 5 N/mm1 slider stepestimated range

    Range: 40 – 220 N/mm · Default: 120 N/mm

    Front axle roll resistance (N/mm). Stiffer = less relative front grip. (unit cited by community sources, range estimated)

    What changes when you move it this way

    Softer front = more front grip and rotation; fixes understeer.

  2. 2.Rear anti-roll bar

    Raise ↑ by 5 N/mm1 slider stepestimated range

    Range: 30 – 200 N/mm · Default: 100 N/mm

    Rear axle roll resistance (N/mm). Stiffer = sharper rear and less rear grip. (unit cited by community sources, range estimated)

    What changes when you move it this way

    Stiffer rear = more rotation/oversteer; helps understeer but loosens the rear.

  3. 3.Front camber

    Lower ↓ by 0.2 °2 slider stepsestimated range

    Range: -4.5 – -1.0 ° · Default: -3.0 °

    Wheel lean seen from the front. More negative = more cornering grip, less under braking/straights. (unit confirmed, range estimated)

    What changes when you move it this way

    More negative gives more lateral grip in corners, costing braking and inner-edge temps.

How to apply it without losing your afternoon

  1. 01Change ONE thing at a time and run three clean laps before judging. Two changes at once and you no longer know which one worked.
  2. 02Start with the first parameter on the list: they are in the order the engine applies them, from the one with most authority to the fine tuning.
  3. 03If the change goes the right way but falls short, repeat the same step again before touching another parameter.
  4. 04If it gets worse, put it back. A setup you don't understand is slower than a baseline you do.

Where this sim stores its setups

AMS2 lets you save/load named setups from the garage screen itself (an in-game feature widely documented by the community). The EXACT on-disk file/folder structure could not be verified against a specific public source in this session (unlike ACC/iRacing/rFactor2 in this catalogue, which do have a concrete source) — the verified way to share a community setup is to enter the values by hand in the game's editor.

Want the exact values, not just the direction?

The generator takes your car, your track, the weather, grip and fuel, and returns the full setup with the reasoning behind every number. Free to start.

If that wasn't it

Symptoms get confused with each other: what feels like poor traction is very often oversteer on throttle. These are the other diagnoses for this sim.

The same problem in other sims

Same symptom, different parameters: each game exposes different sliders, with other units and other ranges.
